SAD-IRON.

SPECIFICATION forming part of Letters Batent No. 685,423, dated October 29, 1901.

Application filed June 24, 1899. Serial No. 721,736- (No model.)

To aZZ whom it may concern:

Be it known that I, WILBERT W. LAMB, a citizen of-the United States of America, and

a resident of Sioux City, Woodbury county,

Iowa, have invented certain new and useful Improvements in Sad-Irons, of which the following is a specification.

The object of this invention is to provide improved means for heating a sad-iron and maintaining the same at a heated temperature. v

A further object of my invention is to pro vide a sufficient supply of air to the flamechamber of a sad-iron to insure perfect combustion therein of the heat-supplying medium.

A further object of my invention is to provide means to insure the perfect vaporization of the fluid employed as the heating medium in advance of the burning thereof in the flame-chamber of the sad-iron.

A further object of my invention is to provide improved means for attaching a cover and handle to a sad-iron in such a manner as that said cover and handle may be removed and replaced readily and conveniently.

My invention consists in the construction, arrangement, and combination of the elements hereinafter set forth, pointed out in my claims, and illustrated by the accompanying drawings, in which- Figure 1 is a side elevation of the complete device. Fig. 2 is a vertical section of the device longitudinally of Fig. 1. Fig. 3 is a plan of the device, the cover and liquid-tank being removed. Fig. 4 is a rear end elevation of the device. Fig. 5 is a cross-section of the device on the indicated line v5 5 of Fig. 1." Fig. 6 is an enlarged detail section of the gen erator.

In the construction of the device as shown the numeral 10 designates the base, formed with an interior flame-chamber 11, the side and end walls of, the base rising from and at right angles to the bottom, thus providing a' flame-chamber of great capacityrelative to the exterior dimensions of the base. The

rear end wall of the'base 10 is formedwith a posite sides, which generator is seated in the notch 12 of the rear end wall of the base 10, and the notches thereof engage and receive the edges of said end wall. The generator 13 is formed with a horizontally-disposed trapchamber 14 in its forward end portion, and-a supply-pipe 15 is screwed into said trap-chamber. The supply-pipe is bent laterally'within and extends longitudinally of the upper portion of the flame-chamber 11 of the base 10, forming a sinuous passage for the fluid in the flame-chamber. The supply-pipe 15 extends outward from the flame-chamber through a notch 16, formed at the point of convergence of the forward ends of the side walls of the base 10, and a horizontal coil 17 is formed in said pipe in front of the base. pipe 15 rises from the horizontal coil 17 and is screwed at its upper end into the lower end of a supply-tank 18, arranged and so shaped The supplyas to be supplied with gasolene or similar liqof thewell 20. The lower portion of the generator extends rearwardly from the vertical plane of the well 20 and is horizontally bored,

the forward end portion of the bore being tapered or reduced to a minute port, the said bore communicating with the lower end of the well. A burner 23 is mounted horizontally in the forward portion of the generator 13, below the supply-pipe 15, and extendslongitudinally of the lower portion of the flamechamber 11 in the base 10, and the "forward end of the burner is closed. The burner 23 is mounted in alinement with the bore of the lower rear portion of the generator 13 and receives vapor therefrom, and said burner is formed with three rows of perforations 24 throughout its length and in the lower por- Loo portions thereof.

tion thereof. One row of the perforations 24 opens downwardly from the burner 23, and the other rows of perforations are located on either side of the said row and open toward the bottom of the flame-chamber and at oblique angles to the first. A notch 25 is formed in the lower portion of the generator 13, between the forward end of the lower bore and the rear end of the burner 23, and a drip-cup 26 is formed in a rearwardly-projecting portion of the base 10, immediately below said notch. A needle-valve 27 is screwed in the bore at and transversely of the lower end of the well 20, and the forward end of said needle-valve is cone-shaped and fits in and against the forward portion of said bore and cuts off, when desired, the flow from said bore. A stulfing-box 28 is mounted on the rearwardlyprojecting portion of the generator 13, concentric with the needle-valve 27, anda packing 29, of asbestos or similar suitable material, is located in the stuffing-box and surrounds and contacts with the valve. The needie-valve 27 extends rearwardly from the stuiiing-box 28 and is made angular for engagement by a wrench or key (not shown) of common form, whereby said valve may be r0- tated. Ventilating-pipes 30 31 are mounted in and longitudinally of the lower side corners of the flame-chamber 11 and extend through the rear end wall and the forward end portions of the side walls of the base 10. The ventilating-pipes 3O 31 are open-ended and rigidly mounted in the base and are formed with upwardly-opening ports 32 in rows throughout their lengths and in the top The upper margins of the intermediate portions of the side walls of the base 10 are cut away and notched below the horizontal plane of the top of the forward ends thereof to provide space for the escape freely of the air from the flame-chamber 11. Ventilating-ports 33 34 are formed in the lower portions of the side walls of the base 10, which ports are inclined, entering the side walls below the tops of the ventilating-pipes 3O 31, traversing said walls obliquely upwardly,and entering the flame-chamber 11 in the plane of the tops or above the said pipes, the inner openings of the ports being wholly above the outer openings thereof. By reason of the inclined positioning of the ports 33 34 the atmospheric air must enter the flame-chamber in an upwardly oblique direction and direct the escape of the air from the flame-chamber through the notches and spaces at the tops of the side walls of the base. Holes 35 36 are formed in the upper portions of the rear end wall of the base 10, and a cover 37 is formed with rearwardly-projecting pins on its rear end entering said holes. The cover 37 extends over the flame-chamber 11, and the forward extremity thereof enters the converging space between the converging forward ends of the side walls and is retained by a hook 38, pivotally mounted in a vertical aperture or seat in one of the side walls and adapted to be the base 10.

turned manually to engage the upper side of the cover. A stud 39 is formed on and extends downwardly from the rear end of the lid 37 and engages the upper face of the generator 13, and thus the generator is held against upward movement from its seat in Standards 40 41 are formed on and rise from the ends of the cover 37, and a handle 42 connects the upper ends of said standards. A shield 43 is mounted between the handle 42 and the cover 37, whereby the hand of the operator is protected from the heat of the sad-iron.
